[Elecraft] Recommended Power for K3/100 for 100% Data Modes

[Eric KG6MZS]

Hello All,

I’ve searched the reflector's archives and haven’t found anything on this, so here goes.

I have an aging K3/1000 (sn 3045) and I wish to preserve its operating life.  Up until now I’ve mostly operated in SSB and BPSK.  Recently I’ve been exploring some 100% duty cycle modes and I am wondering what would be a prudent power level for these modes.  Or perhaps there is a temperature limit that should be observed on the KPA3’s heat sink?

Suggestions?

TIA,
Eric Fitzgerald
